An account of Dr Junod's experiences between 1935 and 1945 on missions which took him first to Abyssinia and air raids with mustard gas bombs, then to Spain, Poland, Germany and lastly to Japan, where he was one of the first foreign doctors to observe the horrific effects of the atom bomb dropped on Hiroshima. Through Dr Junod's narrative, the reader discovers the difficult and sometimes dangerous, but always fascinating, work of an ICRC delegate.
